Maximum PC: Microsoft took its sweet little time bringing a wireless PC adapter for Xbox One controllers to market, and when it finally arrived, the Redmond outfit said it would only support Windows 10 because of, well, reasons. Users who haven't upgraded to Windows 10 can stop pounding sand over the snub. Microsoft's Major Nelson (Larry Hryb) announced on Twitter that in addition to Windows 10, the adapter now supports Windows 7 and Windows 8.1.
